I fucking love X-COM. Well, the first two games. Apocalypse is dead to me.
I've never played either of the sequels. I recall hearing that Terror from the Deep (or whatever the hell it was called) was pretty much the exact same thing. True? What was the problem with Apocalypse?
I'd kill for a turn-based squad combat game with modern graphics along the lines of X-COM![]()
TFTD was similar, but harder. They swapped out the graphics and amped the difficulty.
Which is why I've never played it. I can't even survive more than a few missions in the original game...

Pulling out older games happens to me a lot. To name just a few:
Homeworld
SimCity 4
Tom Landry's Strategy Football
Space Quest III
